Cov Kev Cov nyom ntawm Kev Hloov Kho Ncaj Qha

1. Kev Sib Hloov Kev Ncaj Ncees ntawm Cov Teeb Liab

Cov nonlinearities uas tau tsim thaum lub sijhawm modulation ncaj qha tuaj yeem ua rau cov teeb liab tsis sib xws, tshwj xeeb tshaj yog thaum muaj ntau zaus dua. Qhov no txwv tsis pub ua haujlwm hauv cov xwm txheej xa cov ntaub ntawv ceev ceev.

2. Kev Txwv Bandwidth

Piv rau cov txheej txheem modulation sab nraud, cov kab ke modulated ncaj qha yuav ua rau pom qhov bandwidth nqaim dua, txwv tsis pub siv rau hauv cov ntawv thov ultra-high-frequency.

3. Environmental Sensitivity

thaum uwb ua feem ntau muaj zog, cov txheej txheem kev hloov kho ncaj qha xav tau kev kho kom zoo kom txo tau cov teebmeem ntau txoj hauv kev hauv cov chaw muaj kev cuam tshuam ntau.

Cov Ntawv Thov Tseem Ceeb ntawm Cov Transmitters UWB ncaj qha

1. Cov Txheej Txheem Qhia Chaw Nyob Tam Sim No (RTLS)

UWB qhov kev daws teeb meem ntawm lub sijhawm uas tsis muaj qhov sib piv ua rau muaj qhov tseeb ntawm qib centimeter hauv kev teeb tsa qhov chaw, ua rau muaj kev hloov pauv loj hauv kev lag luam uas nyob ntawm kev taug qab meej:

Cov Khoom Siv Tseem Ceeb:

Kev Siv Tshuab Rau Hauv Tsev Khaws Khoom: Taug qab AGVs (Cov Tsheb Uas Muaj Kev Qhia Tsis Siv Neeg) thiab cov khoom muag nrog qhov tseeb qis dua 30 cm.

Kev Kho Mob: Saib xyuas cov khoom siv kho mob thiab kev txav mus los ntawm cov neeg mob hauv tsev kho mob.

Kev Tshawb Fawb Txog Kev Ua Si: Kev taug qab cov neeg ncaws pob tiag tiag rau kev ua kom zoo dua.

Kev Sib Tw Zoo Dua Lwm Txoj Hauv Kev:

UWB ua tau zoo dua Bluetooth thiab Wi-Fi hauv ntau qhov chaw muaj ntau txoj kev, xa qhov tseeb ntau dua 10 npaug. Nws txoj kev tiv thaiv kev cuam tshuam ua kom ntseeg tau tias muaj kev ntseeg siab hauv cov chaw lag luam uas muaj neeg coob coob.

2. Kev Sib Txuas Lus Ceev Ceev Wireless

UWB qhov dav spectrum (500 MHz txog ntau GHz) txhawb nqa kev xa cov ntaub ntawv gigabit, ua rau:

Kev Tshaj Tawm Multimedia Tsis Muaj Kev Sib Txuas**: Kev xa cov yeeb yaj kiab 8K thiab cov ntsiab lus AR/VR uas tsis muaj kev poob qis los ntawm wireless.

Kev Sib Txuas IoT: Kev sib txuas lus qeeb rau cov khoom siv hauv tsev ntse thiab cov sensors kev lag luam.

Cov Tes Haujlwm Thaum Muaj Xwm Ceev: Cov tes haujlwm ad-hoc muaj zog hauv cov xwm txheej muaj kev puas tsuaj uas cov khoom siv ib txwm ua tsis tiav.

Cov Qauv Tshiab:

UWB yog ib qho tseem ceeb rau IEEE 802.15.4z, txhim kho kev nyab xeeb rau kev nkag mus rau hauv tsheb yam tsis tas siv tus yuam sij thiab kev them nyiaj yam tsis tas kov.

3. Muaj Automation

Hauv kev tsim khoom thiab kev siv neeg hlau, UWB daws cov teeb meem tseem ceeb:

Kev Taw Qhia Tseeb: AGVs zam kev sib tsoo siv UWB-enabled real-time positioning, txawm tias nyob rau hauv GPS-denied chaw.

Kev Nyab Xeeb ntawm Cov Neeg Ua Haujlwm: Cov tshuab ntes qhov ze ceeb toom cov neeg ua haujlwm nyob ze cov tshuab txaus ntshai.

Kev Txhim Kho Cov Txheej Txheem: Kev taug qab cov khoom muaj nqis tiag tiag txo cov sijhawm tsis ua haujlwm hauv cov chaw tsim khoom semiconductor thiab cov chaw tsim khoom tsheb.
